VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 357,798. dated February15, 1887.

Application liled February 3, 1886. Serial No.190,740. (No model.)

To all whom it may concern:

Beit known that I, WILLIAM WAi-NWEIGHT, ofthe city and county of SanFrancisco, State of California, have invented an Improvement inVapor-Burners; and I hereby declare the following to be a full, clear,and exact descrip tion ofthe same.

My invention relates to the class of burners which are used for burningthe vapor arising from the lighter or more volatile oils, such asgasoline, naphtha, dto.; and my invention consists in theconstructionand combination of devices, all of which I shall hereinafterfully describe by reference to the accompanying drawings, in which-Figure l is a view showing the pedestal of a lamp in elevation and itsreservoir, wicktube, and burner in vertical section. Fig. 2 is averticalsection showing the burner-valve. Fig. 3 is a modification of saine.Fig. 4 is a vertical section showing the flanges attached to a sleevefitted on the burner-tube.

rIlhe object of my invention will appear in the course of the followingdescription.

A is any form of lamp-stand, having an oilreservoir, B, with the usualscrew, b, in its top.

C is the wick-tube having a threaded hanged base, whereby it is screwedinto the oil-reservoir. Upon the lower portion of this tube is formed orsecured in any suitable manner a spiral thread or screw, D, upon whichis seated a threaded collar or nut, d, provided with ears d, from whichtwo small rods, E, extend npwardly, and are united at their tops toaplate, F.

G is an annular socketed piece or seat internally threaded and having atubular stein, g', saidpiece and stem being fitted on the tube C. Theplate F is seated loosely in a groove, g, in said stem.

H is the wick, which extends from the oilreservoir through the wick-tubeC.

I is the burner-tube, consisting of a short pipe tting over the top ofthe wick-tubeC and having an eXternalIythreaded flange, c', on its base,which is screwed into the' socketed piece G, packing y being placedwithin said socketed piece so as to make a vaportight joint.

The operation of the mechanism as far as described is as follows; Byturning the nut d upon the screw D so that it rises, the plate F abovealso rises, forcing upwardly the socketed piece G, and thus causing theburner-tube I to move up 011 the wicletube C. the nut d down again theplate F draws the socketed piece and the burner down. The ob` ject ofthis ad)- ustment is to regulate the amount the point of ignition andthe top of the wick. Thus when the burner is'moved down a greater heatis thereby obtained, which generates more vapor and causes an increasein the body of there is less heat and consequently less vapor generated,and the size of the flame is thereby reduced.

J is a heating and directing flange, which is secured on the top of theburner. This ilange has a fanshape in outline, and is concave on itssurface next to the flame. It may be secured directly to the top of theburner, as shown in Fig. 3; or it may be secured to a small sleeve, j,which is adapted to fit over the top of the burner-tube, as is shown inFig. 4.

The flange J is hinged to the top of' the burner in any suitable manner,asis shown by the horizontallyarranged pintlej, Fig.l, passburner andthe base ofthe flange. From the flange extends downwardly an arm, j?,through which passes a screw, j, which bears against the side of theburner. By turning this screw the burner it will be seen that the flangeis thrown forwardly over the top of the burner, While by reversing themovement of the screw it is drawn backwardly. This hinge may be as shownin Fig. l, or it may be hinged to the sleeve j, which is iitted over thetop of the burner, as is shown in Fig. 4. The object of the flange is toincrease the vapor generating heat, and also to spread the ame to a fanshape, its construction being adapted for this purpose.

The object of' hinging the ange so as to render it adjustable is asfollows: In the first Vhen forced over the burner, the vapor-jets,comingincontactwith the fiangemore quickly, have less opportunity togather oxygen from the air, and the flame is therefore darker and ingthrough suitable sockets on the top of the- By turning 55 of flamedesired, which is accomplished byin- `creasing or decreasing thedistance between 6o the flame, and when the burner-tube is raised insuch a way as to withdraw the arm from connected directly with the topofthe burner, 9o

place, it regulates the quality of the fiame. Ico

emits a greater quantity of smoke, showing an imperfect combustion. Whenthe flange is moved back, the points at which the jets strike it beingfurther removed from the ports throuoh which the vapor escapes, there ismore oxygen gathered and the flame burns whiter and with less smoke. Bythe movement ofthe iiange I can therefore regulate the qualityof thelight. In the next place, the movement of the flange enables theoperator to get at the ports in the valve and to clear them out whenthey become stopped up from any cause. The iiange J may be used alone,as is shown in Fig. 4, or it may be used in connection with asupplementary flange, K, such as is shown in Figs. l, 4. This ilange maybe straight or curved, and is preferably made smaller than the flange J.It may be hinged as said flange is, or it may be fixed in position. Itforms, with the flange J, a large open-ended slot across the top of theburner, and assists in the heating and spreading effect.

The burner may be made with a top having minute perforations madedirectly through it, as shown in Fig. 1, and these perforations arepreferably made obliquely and in such a way that thejets of vaporemitted from each will cross those from the other, as in an ordinarymetal gas-burner.

Across the top of the burner-tube is made a socket, M, having a pluggedend, an open end, and an aperture, m,inits middle. i Theburnertubecommunicates with the socket by a small passage, m', near the pluggedend. Vithin this socket is fitted the spigot-valve N, having anopen-inner end, which communicates with the passage m', and havingminute perforations '1L in its body, which are just under the aperture min the socket. These perforations may be made in any number and ondifferent sidesas, for example, I could have one on one side,

two on another, three on another, and so onwhereby upon turning saidvalve the different sets of ports may be brought into communication withthe aperture m in the socket and a greater or less light obtained. Thespigotvalve projects from one end of its seat, and

may be turned by a suitable key. The valve and its seat may be arrangedhorizontally, as shown in Fig. 2, or at an angle, as shown in Fig. 3.

O is a shade-bracket consisting of wire arms secured in a collar, 0,which is tted in the groove gIZ of the stem g of piece G above the plateF, so that said collar has a iirm supportand moves up and down with theburner. In case I wish to provide for the' removal of the shade-bracket,I screw the downwardly-extending stem g of piece G intointernallythreaded lock-nuts P, seated on the wick-tube C just above thethreaded portion D thereon. By unscrewing the socketed piece G it can betaken otI, whereby the shade-bracket may also be removed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters 1. The wick-tube C, having a spiral thread or screw,D, and the burner tube I, resting upon the top of said wick-tube, incombination with a threaded exterior nut traversing the screw D, aplate, F, and the rods E, by which said plate is. connected with thenut, whereby the burner is vertically adjusted, substantially as hereindescribed.
